Integration Middleware
Redox Integration
Redox is an integration platform (middleware) that lets your application connect to many different EHRs through a single, consistent API — instead of building and maintaining a separate integration for Epic, Cerner, MEDITECH, and each other system. For digital health products that need to scale across many health systems, Redox can dramatically reduce the per-customer integration burden. This guide explains how Redox works, when to use it, the setup path, and the compliance picture.
How Redox works
Redox sits between your application and the health system's EHR. You integrate once with the Redox API (which supports both its data models and FHIR), and Redox handles the translation to and from each EHR's specific interfaces — whether modern FHIR, HL7 v2, or proprietary connections. When you onboard a new health system, much of the work shifts to configuring a connection rather than writing new integration code. Redox also manages a great deal of the connectivity, monitoring, and transformation that you would otherwise build and operate yourself.
When to use middleware like Redox
Integration platforms make the most sense when you need to reach many health systems and want to minimise bespoke per-EHR engineering and ongoing maintenance. The trade-off is a dependency and cost layer between you and the EHR, and sometimes less low-level control than a direct integration. Many products use a hybrid approach — middleware for breadth and speed across many customers, with direct integration where a specific deep capability or economics demands it. The right choice depends on your scale, margins, and how deep your EHR interactions need to be.
Compliance with middleware
Using middleware does not remove your compliance obligations. Patient data still flows through your systems and the platform, so you need a Business Associate Agreement with the middleware provider, and your own application must still meet HIPAA, UK GDPR, and relevant security standards. The benefit is that a mature platform brings its own robust security and connectivity, but you remain accountable for how data is used and protected in your product.
How to integrate with Redox
- 1
Sign up and sign a BAA with Redox
Establish a Redox account and the Business Associate Agreement covering patient data flowing through the platform.
- 2
Integrate once with the Redox API
Build your application against Redox's API / data models (and FHIR), mapping your data to its standardised structures.
- 3
Test in the Redox sandbox
Validate your data flows and message handling against Redox's testing environment before connecting live systems.
- 4
Onboard health-system connections
For each customer, configure the Redox connection to their EHR rather than writing a new integration.
- 5
Monitor and maintain
Use Redox's monitoring alongside your own observability to ensure reliable data exchange in production.
Common use cases
- Scaling a digital health product across many EHRs with one integration
- Reducing per-customer engineering and maintenance for integrations
- Bridging modern apps to legacy HL7 v2 environments via one platform
- Accelerating time-to-go-live when onboarding new health systems
Workflow example
Multi-EHR app onboarding
- Your app integrates once with the Redox API and is validated in the sandbox.
- A new hospital customer signs on; Redox configures the connection to their EHR.
- Patient data flows bidirectionally through Redox in your standardised format.
- Your team monitors the connection and ships the same product to the next customer faster.
Frequently asked questions
Does Redox replace building my own EHR integrations?
For many use cases, yes — you integrate once with Redox and reach many EHRs through it, instead of building per-EHR. Some products still pair it with direct integrations where deep, system-specific capability or economics require it.
Does Redox support FHIR?
Yes. Redox supports FHIR alongside its own data models and legacy interfaces like HL7 v2, translating between your application and whatever each EHR exposes.
Do I still need a BAA when using Redox?
Yes. Patient data flows through the platform and your systems, so you need a Business Associate Agreement with Redox, and your application must still meet HIPAA, UK GDPR, and applicable security standards.
